At the Crypto 2004 conference in Santa Barbara, Calif. last month, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren’t cause for ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

The developers of two open source code libraries for Secure Shell, which is the protocol used by millions of computers to create encrypted connections, have decided to no longer support the Secure ...

CYB-SHA3 implements Secure Hash Algorithm-3 (SHA-3) family of functions on binary data with the NIST FIPS 202 Standard. It supports cryptographic hash ...

The Secure Hash Algorithm version 3 fixes flaws in the now-standard SHA-2 cipher. Here's how to prepare for a migration to SHA-3 when SHA-2 is inevitably compromised. Over the last two years, most of ...

Download this article in PDF format. On the surface, this sounds ridiculous: A lobby fish tank gets attacked by hackers. Why would anyone want to break into a fish tank (Fig. 1)? But in this case, the ...

There are two fundamentally different authentication schemes: symmetric systems, which rely on secret keys shared by host and authenticator, and asymmetric systems, such as the Elliptic Curve Digital ...
